Hi All, I would like to know for a cloud setup , what are the detail

@mohamedt Hi, do you have the process ids in hand? If so, they are more than enough and raise a support case by specifying the process ids you need to unarchive. Otherwise you may need to come up with the some criteria such as instances archived between a date range or instances of a particular model or a combination of thereby and so on. Cloud Team will use these search criteria later on and will prepare queries accordingly which thereby results in unarchival of instances in desired way. In this case, you may also opt for a Shared Component at http://bit.ly/1UdxI1X which will archive/unarchive the process instances provided if you have process ids at hand. Downside with usage of Shared Component is, you generally lose tracking of what has been unarchived and this can become a issue in future.

Again, if you don't have the process ids and completely not clear re what processes needs to be archived, documentation at https://forum.appian.com/suite/help/16.2/Managing_Process_Archives.html under 'Unarchive and Search Options' will let you know the various search criteria available.

As you are working on a cloud instance, as per my knowledge, the cloud team would be able to let you (or the concerned person dealing with Cloud Team in your Project) know the various options available.

Thanks for the information @sikivahans ,

It has raised below queries,
1. When a process instance gets unarchived when it will again get archived?
2. For how long archived instances are kept in memory?

1. Until and unless you archive them manually or make use of a process (by making use of components such as Process Management Smart Services), the instances stays in the system forever.
This is the problem with unarchived instances and we should keep an eye on these kind of instances as they may stay forever if we don't archive them back.

2. I will say that it depends on the requirement. In some places clients may ask to maintain the instances for 1 year and in some places, client may ask to maintain for 4 years. Ultimately as it's a file stored on the local file system, I don't think it's a big deal even if we maintain the files for years and years and as long as the files are present, it's not a tough job to bring them back into Appian. Anyhow this answer is made as far as my knowledge is considered and so I would leave it open to others just in case if they have different opinions or views.
